Thanks Bams for your continued interest!
I've taken a video of the test, very tight PSOAS muscles from the looks of things, and certainly something I need to stretch a few times a day at work due to sitting down a lot of the time.
No worries Myst, just wanted to make sure you weren't stretching the wrong muscles and making it worse. Luckily I did.
From the angle, the PSOAS looks a little tight. The RECTUS FEMORIS (part of the quad) on the other hand is definitely tight, there is a greater than 90 degree angle between the upper and lower leg.
Stretching the hamstrings won't do you any good because they're already in an OVERSRETCHED position. Stretching the low back would be good, but it's better if you just focused on the other things instead.
Out of all the current ab/lower back exercises you're doing planks are the only ones I would keep. The ab bike for example, uses the hip flexors and we want to use rectus abdominis (6 pack). Reverse crunches would be a great exercise for this.
To Do List-
* Stretch the hip flexors/quad with a bent leg. Do not stretch the lower back. You can use a couch or chair with a cushion for this. 1-2 times daily, for 30-60 seconds at a time per leg. Longer tensions are better for lengthening a muscle.

* Strengthen the abs, hamstrings and glutes.
* Foam roll the ITB, TFL and quads everyday. If you don't have a foam roller, get one or a 1 metre long 90mm PVC pipe. This will be your neew best friend. You can use a lacross/cricket ball like the guy on the video but will be very painful if you have't built up a tolerance with the foam roller first.
